After a failed install of a microsoft program by my spouse, I found that the firefox browser will not work. My bookmarks will not open, my toolbar links will not open, I can paste an URL into the browser, but it will not open the page. The tab with bookmarks has the list, but none will execute. On the right, the link for "passwords" does not open, so I don't know if they have been saved. I refreshed the browser a number of times with no change. I reinstalled it, with no change. I uninstalled firefox the following day, and then reinstalled. Still no change. I can open no websites, I can do absolutely nothing on this browser. Any suggestions? I've used all of the help links - deleted cache, refreshed over and over. Nada

You can check for issues caused by a corrupted or incomplete Visual C++ installation that is missing runtime components (Redistributable Packages) required by Firefox, especially VCRUNTIME140_1.dll.

Install both 32-bit and 64-bit "Visual Studio 2015, 2017 and 2019" downloads, (x86: vc_redist.x86.exe and x64: vc_redist.x64.exe) from https://support.microsoft.com/help/2977003/the-latest-supported-visual-c-downloads

You may not need the latter (32-bit version) if you use 64-bit Firefox. You may have to reboot the computer. ++++++++++++++++++++++++++++++++++++++++++++++ In another thread, a user reported that a recent update of Malwarebytes Anti-Exploit (version 415) may be causing symptoms similar to the VC Runtime problem. If you have MBAE, it should have a setting to exempt Firefox. You could test whether that makes any difference.
